Sleep Number c2 vs. c4: What’s Best for You?

Sleep Number C2 Vs C4 Cropped (1)

The Sleep Number c2 and c4 mattresses are part of the Sleep Number’s “Classic Series.” This means they have lesser features compared to other Sleep Number products. They will, however, provide dynamic support and are less expensive than most Sleep Number alternatives.

Before diving into the main differences and similarities between these two beds, let’s look at the exceptional features of Sleep Number mattresses.

Each Sleep Number mattress is an airbed. All their mattresses have a remote control that lets you change the amount of air in their air chambers to help you find your ideal “sleep number” and firmness level. 

Moreover, all sides of the Sleep Number mattresses are adjustable and customisable, making it a good option for married people who have different preferences on how firm or soft their mattress should feel.

Sleep Number c2 Mattress

The c2 bed, unlike all other Sleep Number beds, does not have a foam mattress pad on the upper part of its air chamber. Instead, it comes with a thin layer of soft fiberfill stitched into the top of its air chambers. This is excellent for side sleepers and people who prefer firm beds.

Sleep Number c4 Mattress

The Sleep Number c4 mattress has an extra comfort layer that moulds to the shape of your body.

Furthermore, it has unique technological integrations that work perfectly with SleepIQ® technology, which tracks and records what you do while you sleep.

Similarities between the Sleep Number c2 and Sleep Number c4 Mattresses 

These two mattresses are so similar that if you tried them both out randomly, you would probably not be able to differentiate them. The following are some similarities between the two mattresses:

They’re adjustable: One major feature of every Sleep Number mattress is the ability to instantly inflate or deflate them, making them feel firmer or softer. The degree of comfort you choose depends on your personalised sleep number setting, which ranges from 0 to 100.

They’re firm: Their model numbers run from 2 to 10, showing your bed’s softness or firmness level. The names “c2” and “c4” indicate that these mattresses will be firm because c2 doesn’t come with the comfort foam layer on top of their air chamber, while c4 offers a thin one.  

Both mattresses are considerably firm, making them ideal choices for people who sleep on their backs.

They’re part of the Classic Series: c2 and c4 are the only two bed options in the Classic Series. The 360° Smart Bed Series includes all the other versions of Sleep Number mattresses, which means they’ll include technologies such as the auto-adjustability feature, which records and adapts to your natural motions over the night. On the other hand, the Classic Series is significantly cheaper and less vulnerable to tech fixes because the beds come with fewer features.

Same warranty: The c2 and c4 mattresses have a 25-year warranty. According to their agreement forms, Sleep Number will fix your mattress or issue a new one if the previous one has a default that wasn’t caused by human error for the first two years. 

From the 3rd to the 25th year of the warranty coverage, you will have to pay a part of the costs of repairs and replacements. Sleep Number will determine the precise amount by considering the current cost of the mattress. However, since Sleep Number’s prices often change over time, it’s not easy to figure out how much it will cost.

They are compatible with the SleepIQ technology: You may integrate your mattress with SleepIQ for an additional $150. This feature allows the mattress to record your sleep activities and provide you with a thorough evaluation of your sleep patterns the following day. These are the only Sleep Number beds that require you to pay additional charges for these features; all other models come with these features at no extra cost.

Differences Between the Sleep Number c2 and c4 Mattresses

Here are the main differences between Sleep numbers c2 and c4. These features will help you decide which bed would be best for you.

The c4 has more padding: The c2 mattress lacks a top layer of comfort foam. Instead, they come with a thin sheet of soft fiberfill stitched into the top of their air chambers. On the other hand, the c4 models have a 1.5-inch thick foam comfort layer. It is created using polyurethane foam and has three “zones of comfort” to relieve pressure on your head, back, hips, and neck.

Mattress profiling: c2 mattresses are 8 inches thick, whereas c4 mattresses are 10 inches thick. A mattress’s profile is determined by measuring it from the bottom to the top.

Price

Pricing for c2 and c4 beds varies greatly. Here’s a pricing comparison chart:

Bed Size Size Dimensionc2 Pricec4 Price 
Twin38” x 75”$499.99$1,399
Twin Long38” x 85”$599.99$1,499

Twin38” x 75”$499.99$1,399

General Comfort and Feel

The c4 design features a 1.5-inch comfort foam; therefore, it feels softer than the c2 model. The comfort layers are intended to support your neck, head, and neck, so if you’re looking for more luxurious comfort, the c4 could be your best option.

The hardness of Sleep Number mattresses is partly determined by their air chambers and your personalised sleep number. In other words, both beds will have a sturdy and firm feel. However, with the $700 margin between these two beds, you’ll need to determine if the comfort layer is necessary.

Who Should Consider Buying the Sleep Number c2 Model?

Here are two main reasons you should consider getting a c2 bed:

  • If you are looking for the cheapest solution, a c2 mattress is significantly less expensive than other Sleep Number mattresses. Most customers claim that Sleep Number mattresses are expensive and subject to technical problems. So, If you’re on a tight budget but still prefer a Sleep Number mattress, the c2 model will offer you a customisable mattress at a reasonable price.
  • If you are suffering from back pain: No mattress brand can replace medical advice, but countless customers have confirmed that the c2’s firmness offers substantial and long-lasting support that can relieve back pain. One customer stated that the c2 mattress offers excellent support for people sleeping on their backs and outstanding support for side sleepers.

Who Should Consider Buying the Sleep Number c4 Model?

  • If you’re seeking an additional layer of comfort: According to several reviewers, the velvety and moulding properties of the comfort layer are a pleasant addition to the hard c4 mattress. In some cases, adding an extra layer of foam might be beneficial!
  • If you’re a heavy user: Sleep Number promises that its beds can support up to 400 pounds on each of their four sides. However, the c4 is best suited to support heavier users since it has an additional layer and cushion.  

The Sleep Number c2 and c4 are excellent choices if you’re looking for a firm bed, you can adjust to your preferred firmness level. However, even a minor feature — or the lack of it —  might significantly impact your sleep pattern, so pay more attention to what you truly need when choosing a mattress.

Air-Pedic Mattress as an Alternative

Air beds are generally more expensive than other mattress types. However, the Air-Pedic 800 Series mattress from Selectabed is the best option if you want the best value. In light of its features and quality, this 13.5-inches air bed is our top pick.

For more airflow and pressure relief, the Air-Pedic 800 Series Bed has a 1.5-inch gel-infused support layer on top of a sensitive 1-inch hypergel soft top layer. While its second layer is less buoyant than the first, it keeps you from sinking too deep into the bed. Next is the 1.5-inch HD Flex Comfort layer supports your curves while providing additional comfort and pressure relief. Although Air-Pedic Mattresses are probably the best alternative to Sleep Numbers c2 & c4, we have ranked the other top 5 competitors here on Sleepify.

A 2-inch Resili-Flex support layer sits between the bed’s air chambers and foam layers, providing extra pressure relief. Due to its ultra-flexible urethane structure, the six-chamber multi-zone air system at the bottom is designed to ensure proper spine alignment. You may adjust the lumbar support independently and use your smart device’s Bluetooth connection to operate it wirelessly.

Experience the difference for yourself – use Sleepify700 for $900 off the Air-Pedic 800 Bed.

Best For: 

  • Hot sleepers: The Air-Pedic 800 Series is designed to keep sleepers cool and comfortable all night. It has air chambers that you can change and different gel-immersed and cooling foam surfaces. It has an add-on Airflow Transfer System that enables a bi-directional flow of air, making it perfect for hot sleepers.
  • Couples: Married people don’t have to debate on the firmness level of their mattress because each side can be adjusted separately, and each person has their remote. This design is also available in four king sizes.
  • People experiencing back pain: The Air-Pedic’s support control promotes proper spine alignment, ultimately reducing the risk of back discomfort.
  • Value seekers: The Air-Pedic 800 Series is more affordable than other adjustable air beds of the same quality.

Not Best For: 

  • People on a tight budget: While the Air-Pedic 800 mattress is our first choice for the best value mattress, they are more costly than the regular beds. Therefore, individuals on a tight budget may be unable to afford them.
  • People who dislike technology or accessories: This isn’t the right mattress for people who find modifications and add-ons complicated. Additionally, if you have simple sleep preferences, you probably don’t need this mattress.

Final Verdict

Before choosing a Sleep Number mattress, evaluate how much more cushion you need. Most air technology beds relieve pressure points, but the c2 and c4 mattresses are the firmest and most basic models. These mattresses are ideal for back and side sleepers. 

If you prefer bounce and don’t need many cushions, the c2 bed may be for you. It’s inexpensive, firm, and without bells and whistles. The c4 mattress, on the other hand, uses the c2 mattress technology and includes a layer of comfort foam to the stiffness.
